Halfway Between 80 and 909

When you ask "What number is halfway between 80 and 909?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=80 and Y=909.

Halfway Between Line

To find the number halfway between 80 and 909, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 909 into our formula, we get:

(80 + 909)/2 = 494.5

Thus, the number halfway between 80 and 909 is 494.5.

To check that our answer is correct, we subtract 80 from 494.5 and subtract 494.5 from 909 and compare the two numbers:

494.5 - 80 = 414.5
909 - 494.5 = 414.5

As you can see, the halfway number is 414.5 higher than 80 and 414.5 lower than 909. Therefore, our halfway between answer of 494.5 above is correct.
